DIESEL ENGINES
CAUTION!
Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and may decrease corrosion
protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Technology (HOAT) engine coolant (antifreeze) or
any “globally compatible” coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the cooling system in an emergency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an authorized dealer as soon as possible.
 Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the
radiator engine coolant and may plug the radiator.
 This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze) is not recommended.

Engine Coolant We recommend using Mopar® Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT (Organic Additive Technology) or equivalent meeting the requirements of the
manufacturer Material Standard MS.90032.
Engine Oil — 3.0L Diesel Engine We recommend using Mopar® API Certified SAE 5W-40 Full Synthetic Engine Oil which
meets the requirements of the manufacturer Material Standard MS-12991. Equivalent
full synthetic SAE 5W-40 engine oil can be used but must be compliant to API SN/SP and
ACEA A3/B4 specifications.
Fuel Filters — 3.0L Diesel Engine We recommend using Mopar® Fuel Filter. Must meet 3 micron rating.
Using a fuel filter
that does not meet the manufacturer filtration and water separating requirements can
severely impact fuel system life and reliability.

CHASSIS FLUIDS AND LUBRICANTS
Fuel Selection — 3.0L Diesel Engine Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law
requires that you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm
Sulfur maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500 ppm
Sulfur maximum) to avoid damage to the emissions control system. For most year-round
service, Number 2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide
good performance. We recommend using a blend of up to 5% biodiesel, meeting ASTM
specification D-975 with your diesel engine.
This vehicle is compatible with biodiesel blends greater than 5% but no greater than 20%
biodiesel meeting ASTM specification D-7467 provided the shortened maintenance
intervals are followed as directed.
Diesel Exhaust Fluid — 3.0L Diesel Engine Mopar® Diesel Exhaust Fluid (DEF) (API Certified) or equivalent that has been API
Certified to the ISO 22241 standard. Use of fluids not API Certified to ISO 22241 may
result in system damage.
Component
Fluid, Lubricant, or Genuine Part
Automatic Transmission – If Equipped Use only Mopar® ZF 8 & 9 Speed Automatic Transmission Fluid (ATF) or equivalent.
Failure to use the correct fluid may affect the function or performance of your
transmission.
Manual Transmission – If Equipped We recommend using Mopar® ATF+4 Automatic Transmission Fluid.
Transfer Case We recommend using Mopar® ATF+4 Automatic Transmission Fluid.
Front Axle Differential We recommend using Mopar® Gear & Axle Lubricant (SAE 75W85)(API GL-5).
Rear Axle Differential (M200 Sales Code DRZ) We recommend using Mopar® Gear & Axle Lubricant (SAE 75W140)(API GL-5).
Rear Axle Differential (M220 Sales Codes DRE/DRF) We recommend using Mopar® Gear & Axle Lubricant (SAE 75W85)(API GL-5). Models
equipped with Trac-Lok Limited Slip Differential require a friction modifier additive.
Brake Master Cylinder We recommend using Mopar® DOT 3 Brake Fluid, SAE J1709.
Power Steering Reservoir We recommend using Mopar® Electric Steering Pump Fluid.
